The Sun Kosi, also called Sun Koshi, is a trans-boundary river that originates in the Tibet and it is part of the Koshi or Saptkoshi River system in Nepal.〔Shrestha, A. B., Eriksson, M., Mool, P., Ghimire, P., Mishra, B., & Khanal, N. R. (2010). Glacial lake outburst flood risk assessment of Sun Koshi basin, Nepal. Geomatics, Natural Hazards and Risk 1(2): 157–169.〕 ==River course== The Sun Kosi's headwaters are located in the Zhangzangbo Glacier in Tibet.〔Mool, P. K.; Joshi, S. P.; Bajracharya, S. R. (2001). Glacial Lake Outburst Floods and Damage in the Country. Pages 121–136 in: Inventory of Glaciers, Glacial Lakes and Glacial Lake Outburst Floods: Monitoring and Early Warning Systems in the Hindu Kush-Himalayan Region, Nepal. International Centre for Integrated Mountain Development, Kathmandu.〕 Its upper course, the Bhote Koshi, is known as Poiqu in Tibet.〔Yamada, T., Sharma, C. K. (1993). Glacier lakes and outburst floods in the Nepal Himalaya. IAHS Publications-Publications of the International Association of Hydrological Sciences, 218: 319–330.〕 Both river courses together form one basin that covers an area of about .〔 The Indravati meets the Sun Kosi at Dolaghat, up to where it is followed by the Arniko Rajmarg. From there, the Sun Kosi flows eastwards through the valley formed between the Mahabharat Range and the Himalayas.〔 Tamakosi, Likhu,Dudhkosi,Arun and Tamor are it's left tributaries and Indravati is the right tributary. The average annual flow is 22 x 109 m3. The average sediment load is 54 x 106 m3. The Tamur and the Arun rivers join the Sun Kosi at Tribenighat to form the Saptkoshi, which flows through the Chatra Gorge across the Mahabharat Range on to the Gangetic plain.〔Sharma, U. P. (1996).

Pp 92–99.〕 There are few more smaller tributaries of the Sun Kosi such as Rosi Khola, Junga Khola,and Sapsu Khola. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sun Kosi」の詳細全文を読む スポンサード リンク
